Light Intensity Switches Ex9LA and Ex9LD are used for light switching according to actual daylight intensity (Ex9LD device also according to time), so the light fi xtures are switched only if necessary and it can save money for consumed energy. Analogue version works with one switching channel. Digital version can work with photoelectric and time switch on 2 channels. This switch can automatically change between summer and wintertime.
